# In Ohm v1.2, the Set and MultiSet initialize methods
# are defined on themselves. Hence the trick of doing a
# module OverloadedSet with an initialize method doesn't
# work anymore.
#
# The simplest way to solve that as of now is to duplicate
# and extend the #initialize method for each of these.
#
# Granted it's not the _ideal_ way, the drawbacks are
# outweighed by the simplicity and performance of this
# approach versus other monkey-patching techniques.
